my Aero book pro will not turn on unless you are holding FN Key while powering it up and the second you let go of the key the screen goes black and it shuts down.

I asked Tech and they told me this is hardware problem. That means you need to send it for repair. As this is an old model, i think its out fo warranty, I recommend you to go to a repair store in your city, Maybe is not that deep the problem.
